# Quant Data vs Tradier

Quant Data and Tradier both sit at 4.5 stars, but that hides the real split: 80% of Quant Data's written reviews are positive against 15% of Tradier's. Quant Data also leads on iOS requirement (16.4 vs 18.0). Tradier's advantage is in-app purchases (none vs 4) and ratings volume (658 vs 43). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Quant Data sells 4 in-app purchases, starting at $74.99 per month. Tradier asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for Quant Data against 4.5 for Tradier. That said, the two scores are not equally well evidenced: Tradier has 658 ratings behind it against 43, so its average is the more settled of the two. Written reviews are what separate them: 80% of Quant Data's written reviews are positive against 15% of Tradier's.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on November 14, 2026.
